Wencong Liu commented on FLINK-32686: ------------------------------------- Thanks for reporting this. The second regression since 07.24 is caused by commit id: c9e1833642650e0b1ea162371dd7c6d35f2e21b7. The commit disables the repair in [FLINK-32094] startScheduling.BATCH performance regression since May 11th - ASF JIRA (apache.org) unexpectedly and causes the regression in 07.24. I'll open a pull request to fix this. The first regression in 07.09 is not related with FLINK-32094. > Performance regression on startScheduling.BATCH and startScheduling.STREAMING > since 2023-07-24 > ----------------------------------------------------------------------------------------------- > > Key: FLINK-32686 > URL: https://issues.apache.org/jira/browse/FLINK-32686 > Project: Flink > Issue Type: Bug > Affects Versions: 1.18.0 > Reporter: Martijn Visser > Priority: Blocker > > http://codespeed.dak8s.net:8000/timeline/#/?exe=5&ben=startScheduling.STREAMING&extr=on&quarts=on&equid=off&env=2&revs=200 > http://codespeed.dak8s.net:8000/timeline/#/?exe=5&ben=startScheduling.BATCH&extr=on&quarts=on&equid=off&env=2&revs=200 -- This message was sent by Atlassian Jira (v8.20.10#820010)
